Morykwas et al. present four controlled porcine experiments establishing the preclinical foundation for vacuum-assisted closure (V.A.C.) therapy. The study asks whether controlled subatmospheric pressure applied via open-cell foam improves blood flow, granulation tissue formation, bacterial clearance, and tissue flap survival compared to saline gauze dressings. This is the landmark paper that defined the 125 mmHg treatment standard and the rationale for intermittent cycling.
Every time you set a V.A.C. To 125 mmHg or choose intermittent cycling, you are applying a protocol derived directly from this paper.
When managing a complex traumatic wound or a post-operative dehiscence, the bacterial clearance data gives you a concrete timeline: expect tissue counts to fall below the critical 10⁵ organisms/gram threshold around day 4-5 with V.A.C., versus nearly two weeks with conventional gauze dressings.
For compromised flaps or avulsed tissue with questionable perfusion, pre- and post-operative V.A.C. Application is supported by the flap survival data — both pre-treatment and post-treatment independently improved survival over controls, so initiating V.A.C. After the fact still has benefit.
The companion clinical translation paper by Argenta and Morykwas (Ann Plast Surg, 1997) reported outcomes in 75 human patients across wound types, and together these two papers established negative pressure wound therapy as standard of care for complex wounds in trauma, orthopedics, and reconstructive surgery.
